Blaklion Betting

Blaklion is an eight-year-old trained by Nigel Twiston-Davies, and the former RSA Chase winner will be one of the leading contenders for the 2017 Grand National, which will be the highlight of Aintree's three-day meeting on April 8.

VERDICT: A former Grade 1 winner, Blaklion has shaped into a top quality staying chaser this term, and if he can build on some fine efforts this season then he has to be given huge respect for the Grand National. Obvious chance.
